The Kind of Cabbage that Poo is made of

You may notice that this poo is slightly green. It certainly was. My girlfriend and I are big fans of making okonomiyaki, but we never use a whole cabbage so there's always lots left over. I went and found a recipe for an Apple, Cabbage and Sausage meal. I don't know how to explain it exactly but it's like sausages with sourkraut except that instead of sourkraut, it's shredded cabbage with apples and apple juice in it. Kind of tasty, kind of strange, and apparently it makes your poo green
